Introduction: Atrial fibrillation ablation can be associated with microembolism detected in the intracranial arteries and risk of neurological incidents. The aims of this study were to evaluate microembolic signals (MES) during pulmonary vein isolation (PVI) and establish the potential significance of MES for damage of the brain in radiological investigation and neurological state.
Material And Methods: In the prospective study we included patients with atrial fibrillation undergoing percutaneous pulmonary vein isolation (radiofrequency ablation/balloon cryoablation) with ultrasound monitoring of microembolisms in the middle cerebral artery.
Obesity constitutes a risk factor for atrial fibrillation (AF) and modifies the efficacy of invasive AF treatment. Left atrial (LA) global longitudinal strain (GLS), which is measured using speckle-tracking echocardiography (STE), is one of the new methods that are helpful in evaluating the function of LA. The aim of the study was to evaluate LA function in obese and non-obese patients that were undergoing percutaneous pulmonary vein isolation (PVI) before and 6 months after the procedure.

However, there is no data on the role of FGF23 and soluble Klotho (sKlotho) in the pathogenesis of atrial fibrillation (AF) beyond ESKD. The aim of the study was to assess the peripheral vein and left atrial (LA) serum levels of FGF23 and sKlotho along with calcium-phosphates parameters in patients with AF undergoing percutaneous radiofrequency pulmonary vein isolation (PVI).

Aim: We sought to evaluate plasma renalase concentration in patients with AF undergoing pulmonary vein isolation (PVI) with respect to AF clinical characteristics, left atrial (LA) remodelling, and PVI efficacy.
Methods: This case-control study included 69 patients (median age 58 years) with either paroxysmal (89%) or persistent (11%) AF, referred for PVI, and a control group consisting of 15 patients without AF, matched for age, sex, and comorbidi-ties.
Background: The aim was to assess the occurrence, severity and risk factors for silent white matter hyperintensities (WMH) in brain magnetic resonance imaging (MRI) in patients with atrial fibrillation (AF) and to determine the potential relationship between WHM and cognitive decline.
Methods: Seventy-four patients with paroxysmal non-valvular AF were enrolled (age 59 (IQR 50-63)years, males 45/61%). All patients were on adequate warfarin treatment before inclusion and had no history of stroke or TIA.
Background: Atrial fibrillation (AF) is the most common arrhythmia and is associated with a deterioration of quality of life (QoL). Catheter ablation is a therapeutic strategy for some patients with AF. The effectiveness of pulmonary vein isolation is still under assessment.

Background: Premature ventricular beats (PVBs) and monomorphic ventricular tachycardia originating from the right ventricular outflow tract (RVOT) are the most frequent forms of idiopathic ventricular arrhythmias, but arrhythmia originating from the left ventricular outflow tract (LVOT) may be found in about 10% of these patients.
Aim: To compare electrocardiographic (ECG) patterns and duration of repolarisation after PVBs originating from the left and right superior part of the interventricular septum which were successfully treated with radiofrequency catheter ablation.
Methods: We studied 62 patients who did not receive antiarrhythmic drug treatment before ablation, including 50 patients with RVOT arrhythmia (21 males, mean age 42 ± 14 years, left ventricular ejection fraction [LVEF] 61 ± 6%) and 12 patients with LVOT arrhythmia (3 males, mean age 41 ± 17 years, LVEF 59 ± 9%).
In this review we try to answer the question whether and to what degree contemporary forensic pathology takes advantage of quantitative and qualitative troponin determinations. The report is simultaneously an introduction to discussing our results in this area. To perform this review we used the database "PubMed".
View Article and Find Full Text PDFIntroduction: In patients with atrial fibrillation (AF), significantly symptomatic in particular, restoring and maintaining sinus rhythm is one of treatment strategies. Considering the limited efficacy and side effects of anti-arrhythmic agents, growing hopes are attributed to the developing techniques of percutaneous ablation.
Aim: To determine the efficacy and safety of circumferential pulmonary vein ablation performed using the CARTO system in patients with paroxysmal or permanent AF.
